摘要
自平衡法试桩技术源于钻孔灌注桩试验,已逐步扩展到多个领域,并被多国规范采用,其适应性及经济性在大型桥梁工程及超高层建筑中得到了充分运用。随着自平衡法的推广及超长桩的应用,荷载箱及其设置方式均得到改善和发展。但在平衡点选取及测试数据转换方法上面还存在诸多观点,有待进一步研究。
The self-balanced test technique(SBTT) has been developed on the basis of bored piles testing and applications of SBTT have been extended to different industrial fields. The SBTT is adopted by national codes of many countries and its usability and economy are reflected in large bridge engineering and super high-rise building. With the popularizing of SBTT and application of super long piles, load cell and its setting method have been developed and improved. While, there are many debates on location of balance point and equivalent conversion of date and those debates need to be researched in the future.
